Moscow accuses US of 'boorishness' over Russian flights to Syria

MOSCOW (Reuters) - Russia's Foreign Ministry said on Wednesday that the United States' requests to Greece and Bulgaria to close their airspace for Russian flights to Syria amount to "international boorishness".

The United States asked Greece and Bulgaria earlier this week to deny overflight access, concerned by reports of a Russian military build-up in Syria. Moscow says it is simply helping Damascus fight Islamist militants.
